Liquid Engineering Corporation is the nation's most experienced in-service water storage tank cleaning and inspection service provider. Since 1988, LEC has set the industry standard for in-service water tank maintenance while servicing over 20,000 public and private water clients in 49 states. LEC brings the right resources to every water tank maintenance project. We understand, and solve, the real problems faced by our clients every day. Our tank inspection professionals are equipped with the state-of-the-art equipment, tools and training to work safely and efficiently, regardless of the demands of a specific job or unique environment.
The American Water Works Association currently recommends inspection of drinking water tanks every 3 years. The frequency of cleaning is dependent on sediment accumulation and the requirements of your state and local regulatory agencies. LEC is in recognized compliance with every state's regulatory agency and exceeds the national standards. We are in constant contact with all state agencies and are an on-going resource for local, regional and national regulatory authorities. LEC has worked with State and Federal agencies, most notably the American Water Works Association Water Research Foundation (formerly AWWARF), to research the benefits of cleaning water tanks in-service.
